The case was a 79-year-old woman. She fell on the street in February 2020 and was taken to a nearby doctor complaining of cold numbness in her right hand. She had right humerus proximal fracture and contrast-enhanced CT showed right axillary artery occlusion. She was transferred to our hospital on the third day of her injury. On the 6th day, she underwent open reduction and fixation of the right humerus and revascularization of the right axillary artery. The intraoperative findings showed that the axillary artery was accompanied by thrombotic obstruction in the lumen and damage to the adventitia, but fortunately there was no massive hematoma around the injury. We ligated both the proximal and the distal sides of the adventitial rupture and performed an axillary brachial artery bypass surgery with an autologous great saphenous vein graft. There are two types of reports of arterial injury associated with proximal humerus fractures: thrombotic obstruction due to intimal injury of the artery, bleeding and pseudoaneurysm formation caused by adventitial injury due to bone fragments, In this case, thrombotic obstruction due to intimal injury and adventitial injury were complicated.
